HP Pavilion dv6-1200. USB 'Recognition Problems'

Hello,
Not sure if anyone has had similar or same 'problems'?
With the Laptop directly in front and booted up, when I plug in devices in either USB sockets on the RH Side I have no problems with recognition at first attempt of attaching a device via its USB plug/cable.
When however plugging in to the USB sockets on the LH Side it is a completely different matter, and nine times out of ten, the device is NOT recognised!
When I subsequently remove the USB plug and re-insert it 'Bingo' the device on the end of the plug/cable sometimes gets recognised.
While I am not sure if the 'problem' is Hardware or Software related I would be grateful if anyone has had this problem and identified a solution which they are willing to share please?
The 'problem' has been on/in this machine since purchasing it new from the online HP Store.
Thanks

I'm not quite sure what SM Bus Controller is exactly related to but have you installed AMD Graphics Driver on your Notebook?

Hp pavilion dv6-1355dx USB Problem.

Hello,
I have an hp pavilion dv6-1355dx laptop computer. Recently my HDD crashed and i replaced it with a new one reinstalling Windows 7 64bit. Everything works great, besides my USB's. None of my USB ports work, and in my System devices > Universal Serial Bus Controllers it shows the yellow exclamation point under the multiple "Intel(R) ICH9 Family USB Universal Host Controller -####". I understand the USB support is based in the Chipset software and I have reinstalled this multiple times. This computer is running a T6600 Intel Core 2 Duo with Intel Series 4 Express Chipset. I have also tried to update driver software within device manager and it tells me my driver software is up to date. Does anyone have any insight about this? Below is a screencap of device manager.
Thanks in advance.

Hi, all! I might be bringing up a pretty old topic, but I've registered on this forum, because I've encountered similar problem. I googled and found quite a few people with the same question, some of them on this very forum as well.
The solution provided here didnt work for me, and it took me a few hours to figure out why my controllers kept returning code 37. All usb ports were working fine up until i started updating windows 7 x64 drivers for the dv6-1326ss, downloading them from the official page. The reason why the problem occured was the accidantly installed AMD USB filter driver, so i followed the steps described here, manually deleted all the troubled lines in the divice manager, and rebooted. After the reboot, all of the drivers have succesfully installed from the windows update center, but something tells me, that reinstalling chipset driver would work just as well. Hope that helps somebody.

HP Pavilion dv6-1350sl - USB ports does't work!!

hello,
I have an HP Pavilion dv6-1350sl (bought in Italy, with Windows 7 Home Premium).
Today I formatted my laptop and installed Win 7 Ultimate, however, the USB ports are not working anymore.
I used the drivers contained on HP's own site, but I still have the problem (HP drives Italian).
In Control Panel - System - Device, the USB port is with a yellow exclamation mark (but is energized, tested it with my cell phone).
What can I do? Will I have to reinstall Win 7 Home Premium?
I need help! tnks!!!

We do not know what drivers you tried to install. Is the Win7 Ultimate a legitimate copy? I would try uninstalling the usb hub as a device and reboot to see if you can get the driver to reload properly. Your laptop does not have usb 3.0 so actually Windows 7 ought to have a good driver built in. It is also important to have the Intel chipset driver installed:
http://h10025.www1.hp.com/ewfrf/wc/softwareDownloadIndex?softwareitem=ob-79070-1&cc=us&dlc=en&lc=en&...
If the usb ports were working before the format, then it is very, very unlikely the hardware has failed and it is almost certainly some problem with the OS install.

HP Pavilion dv6 Notebook PC sound problem

hello
I'm having a problem with my laptop that I'd bought two years ago. My laptop audio wouldn't work without USB headphone.
The model is HP Pavilion dv6 Notebook PC
The product number is XG756UA#ABA
Thank you

Hello AustinJeon,
I see that you are having problems with the sound on your HP computer. I have a couple of suggestions that may help with this issue.
Here is a link to some troubleshooting steps for common sound issue. Follow the steps in the link and let me know what happens.
How long have you been having this problem?
If you use the headphone port does it work or is it just USB?

Pavilion dv6-1125es - Hard Disk problem

I have an HP Pavilion dv6-1125es (out of warranty) with Vista Home Premium (32 bit) that runs very slowly and freezes but this does not seem to be caused by malware. I was considering reinstalling but decided to run diagnostics first. In the System Diagnostics (Setup), the Start-up Test (F2) finds no problem in the Memory Test, Hard Disk Quick Test or Hard Disk SMART Test.
In the System Diagnostics Hard Disk Test (F4), the Quick Test indicates Passed (100%) but the Full Test shows:
- 00% Complete
-‘Replace Hard Disk1’(in red) followed by ‘testing’ (in white)
The SMART check indicates Passed
On pressing Esc to continue, the next screen shows (in blue)
- “Hard Disk Test” Failed
- “Hard Disk 1 FULL” (305)
The Diagnostic Log shows Result: 0305
I would be grateful for help with the following points:
1) Is the ‘0305’ error unfixable? Does it mean replacing the hard disk?
2) The current disk is 320 Gb. What is capacity limit for this model dv6-1125es?
3) If I install Windows 7 on the new disk, can the 64 bit version be used on this model?
4) As this laptop has also been running hot, I would like to try to clean the fan and ventilation system. Where can I find instructions on this?
Thanks in advance for your help.
This question was solved.

Hi,
To answer your questions.
1. The 305 error does mean you will need to replace the Hard Drive.
2. You can certainly go up to a 500Gb HDD without any problems - see the procedure starting on Page 69 of your Maintenance & Service Guide.
3. Yes, your processor is 64bit capable - see Here for confirmation of this.
4. There are instructions for cleaning your notebooks air vents Here.

HP Pavilion dv6 Notebook PC Battery Problem

I have an HP Pavilion dv6 Notebook PC Windows Vista 64-bit, I bought it less than 2 months ago. Yesterday I fogot my charging cable so I ran my battery all the way out. Then this morning after charging I turned on my laptop and it gave me a message about the internal battery being weak. I tested it with the HP Support Assistant and got this message:
"The battery is functioning correclty, but due to normal aging of the battery, the battery life between charges has reached a point where your battery is no longer useful. The battery may be covered by your HP Warrant. Please contact HP."
What happened to my battery and is there a way to fix it without getting a new one (highly unlikely but I have to ask..)? I'm hoping this problem is under warrenty because I've only had my laptop for less than two months and the battery is already aged?
Thanks for your help!

Hi, try to download the latest HPSA and test the battery again, if it still shows the same problem, contact local support center to get the battery replaced.

HP Pavilion dv6-6b50sa notebook - Fan problems

Product: HP Pavilion DV6-6b50sa
Operating system: Windows 7 64bit
BIOS version: F.19 05-2012
The fan on my laptop failed earlier during the year and was replaced with a new unit. However since then the fan seems not to run fast enough in response to increased loads on the cpu and GPU. For instance previously when starting a video game the fan would instantly kick up to a higher speed and remain there, cooling the laptop sufficiently. Now the fan will often take a lot longer to get up to speed, and with some games simply refuses to go beyond normal idling speeds even as the temperature increases.
Any help with this? I'm not sure if its a hardware or software issue. When I am back home again I will be replacing the fan with another new one to see. Tried updating the BIOS, have also installed HP coolsense and cleaned out the fan to no avail.
Any help with this would be much appreciated, thanks
Michal

HP Pavilion dv6-6135dx USB 3.0 Problems

Recently bought this laptop, I like it, it works great.
I reformatted pretty much the day I got this laptop. However, I cannot get 2 USB ports on the left side of the laptop to work, I'm assuming these are the USB 3.0 ports. The two USB ports on the right side of the laptop work fine, I'm assuming they are the USB 2.0 ports. Presumably, this is from missing drivers.
I've tried downloading the Renesas Electronics USB 3.0 Host Controller Driver from HP's support website. This does not work. After installing and running the USB 3.0 Host Controller Utility that it installs, a small dialog pops up that says "USB 3.0 Host Controller not found".
In Device Manager, I have two devices that have the yellow exclamation points. One is listed as SM Bus Controller, the other is listed as Unknown device. The hardware IDs for those are:
SM Bus Controller:
PCI\VEN_1022&DEV_780B&SUBSYS_358D103C&REV_13
PCI\VEN_1022&DEV_780B&SUBSYS_358D103C
PCI\VEN_1022&DEV_780B&CC_0C0500
PCI\VEN_1022&DEV_780B&CC_0C05
Unknown device:
USB\VID_138A&PID_0018&REV_0078
USB\VID_138A&PID_0018
Windows Update can't find anything for those two. I've also tried manually selecting the following drivers for the Unknown device and the device will not start still:
1. Renesas Electronics USB 3.0 Host Controller
2. Renesas Electronics USB 3.0 Hub
3. Renesas Electronics USB 3.0 Root Hub
4. Renesas Electronics USB Hub
Although I'm not too worried about the SM Bus Controller, mainly because I have no idea what its purpose is, I'm assuming the USB 3.0 ports is the Unknown device because of the hardware IDs. Help please!

RF Tuner not working correctly in Pavilion DV6-1200

Having troubles tuning the computer to the tv signal. The signal is via a wall cable RF type, Comcast cable.The computer can not detect the source data, however when a normal tv is plugged into the same cable, it tunes into 35 channels. The tv tunes to the signal prior to June 12, 2009 (NTSC). There is no setup box being used. I have used windows media centre and HP media center to tune the computer in but no success yet. The tuner mode I thought that should work is Analog Cable NTSC, plus tried every other mode many times over. The strange thing about this whole matter I was connected to HP tech support for 4 HOURS on this matter! They could not give me any reason why this was happening!!!! The tv tuner does work with the supplied antenna using the Digital Antenna Mode. When I talked to HP tech support, their so called tv tuner experts, they could not tell me what the Analog Cable NTSC mode was used for! Regards, Ed

Hi,
Please uninstall the existing version and install the newer version:

Hi DanielVega
Please boot into the BIOS by pressing F10
In System Configuration change the "action keys mode" this will revert the settings

Try reviewing this post to see if any of the information in it helps you as this case sounds very similar. The thread also has a link to a YouTube video that worked for someone.

Also, did you try the two methods in this document exactly as they are outlined? As long as there is no underlying hardware issue, it should work.

You mentioned you tried the pen drive method and it did not work. What exactly did not work about it? Any error messages? What were the exact steps taken?

Solved Crackling Problem in Windows 7 (SB 24-bit USB External, HP Pavilion dv6 1124-ca laptop).

I'm one of many users who has had problems with the sound crackling problem with their sound card after upgrading to Windows 7.
I was previously on Windows Vista running 5. with 24-bit, 96000Hz sample rate Studio Quality with no problems at all. When I upgraded to Windows 7 RC, Windows was able to automatically find a driver for my external USB sound card, but when playing music, I always got a constant crackling sound coming from the speakers while trying to put the card in anything above 2. or and when putting it in 24-bit 96000Hz, the crackling only got worse. Installing the Beta drivers on the Creative site didn't work either... still had the crackling. I searched around for the past several months for solutions to no avail.
Then today, I was surfing the HP website (I have a HP Pavilion dv6 24-ca laptop) to see if they had added Windows 7 drivers to their support site and they did... and so I started downloading all available Windows 7 drivers for my specific laptop. When I first installed Windows 7 RC, it had installed it's own drivers for everything (on-board sound etc.). After replacing the Windows 7 installed "High Definition Audio Device" drivers with the HP supplied "IDT High Definition Audio CODEC" drivers... I'm not sure if the on board sound driver has anything at all to do with the crackling on the Soundblaster but I replaced the drivers anyway. I also installed another driver called "AMD USB Filter" that was supplied by the HP website for Windows 7 which is another driver that I thought might help with the problem. Other drivers installed were "ENE CIR Reciever Driver" and "Realtek Card Reader Driver" but those have nothing to do with the sound card.
After installing the drivers from the HP website, I no longer get the crackling from the speakers when playing in 5.. I am also now able to select 24-bit 96000Hz sample rate without crackling as well I am very happy to have finally solved the problem. So to anyone having similar problems, I suggest you check out your manufacturers website to see if they have any drivers available for you... I have a feeling the AMD USB Filter is what solved the problem... but who knows.
Hope this helps other HP users!

Try this video let me know if it helps you out.

If you can hear the music through the speakers but not the headphones I would suggest using an AUX cable because seems the sound isn't being transmitted over.

Blue tinted screen, menory problems, underperforming battery - 5 day old HP pavilion dv6-6005sa

I bought a new HP Pavilion dv6-6005sa 15.6" Laptop - Linen White on 14/06/11 from Currys digital, Arndale Centre, Manchester. The laptop is less than 1 week old.
The screen is a frost blue colour from the second I turn it on to the second it is turned off. Weirdly I can see the entire screen, just that everything is blue!! Does anybody know how this can happen??? When I move the screen it flickers from normal to this blue thing. A loose connection maybe?
I am unhappy as I got to send it back to the shop for a under 21 days replacement involving an expensive airmail delivery :@ The alternative would be a 3 week investigation in the lab which I cant be bothered with!
Has anybody else experienced this phenomenon with a HP laptop screen? I also am beginning to experience memory problems and the usb prots are on the blink. I have looked after it very well, it has just been sat on a desk for 5 days! Can anybody explain me this phenomenon and if it is a comon problem with HP laptops?
Now for the next problem as if a faulty screen and memory cache wouldnt be enough! The battery:
The battery specs are as follows:
Lithium-Ion 6-cell battery
'upto 7.5 hours battery life'
The battery is advertised to perform 'upto 7.5 hours' however I get maximum 4.5 hours doing absolutely nothing on power saver mode with the laptop with it just sitting there idle on a desk. At the same time I also had wireless and bluetooth off; screen brightness set to 0%, maximum processing chip power reduced to 20%; battery saver mode active; all major applications closed).
I get maximum 2-3 hours doing basic tasks with it such as word processing. Gaming I get maximum 1.5 hours.
The battery checker displays the following:
Status: Ok (0)
warrenty type: 1 year
cycle count 0
manufacturer: 13-42
battery age 136 days
serial number: 12587 02/01/2011

Cell Voltage 2: 4177 mV
Cell Voltage 3: 4177 mV
Cell Voltage 4: 0 mV
Status: 0
AC Power: True
CT Number: N\A
I have highlighted in bold the things I thing are suspicious. I feel the results are those of a malfunctioning battery. Could anybody tell me if I am correct withmy assumptions?
As I am no expert coes anybody reading this think these results are normal for a new battery and can you provide me some insight to wether my battery might be faulty or not?
Basically I think at least one of the 6 cells inside the battery are malfunctioning.

Go to Power Options in the Control panel and select the Power Saver option. Do not choose balanced. Then run your battery capacity tests again. Hopefully the new setting will improve the time that you get.
